辐射管是一种重要的间接加热设备，被广泛应用于金属热处理、钢坯加热等工艺环节.采用计算流体力学(CFD)技术对辐射管的温度场进行数值模拟，并在相同的操作工况下，对3种常用管型的辐射管的温度均匀性进行对比分析，同时还探讨了壁面黑度对辐射管表面温度均匀性的影响.结果表明：W型辐射管的表面温度均匀性最优，I型辐射管的表面温度均匀性最差；辐射热流量随着壁面黑度的增加而升高，辐射管的壁面黑度在0.7～0.9时，辐射管表面温度均匀性最好.
Abstract：Radiation tube is an important indirect heating device, which is widely used in processes such as metal heat treatment and steel billet heating. The temperature field of the radiation tube has been numerically simulated using CFD technology, and the temperature uniformity of three commonly used shapes of radiation tubes has been compared and analyzed under the same operating conditions. Besides, the influence of wall blackness on the surface temperature uniformity of the radiation tube has been explored. The results show that the surface temperature uniformity of the W-type radiation tube is the best, while the surface temperature uniformity of the I-type radiation tube is the worst. The radiation heat flow rate increases with the increase of blackness. When the blackness of the radiation tube is between 0.7 and 0.9, the surface temperature uniformity of the radiation tube is the best.
